12 Upgrading and downgrading
13 ==========================
18 If you are running an older version, shut it down. Wait until it has completely
19 shut down (which might take a few minutes for older versions), then run the
20 installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
21 bitcoind/bitcoin-qt (on Linux).
23 If you are upgrading from version 0.7.2 or earlier, the first time you run
24 0.9.3 your blockchain files will be re-indexed, which will take anywhere from
25 30 minutes to several hours, depending on the speed of your machine.
30 The 'chainstate' for this release is not always compatible with previous
31 releases, so if you run 0.9.x and then decide to switch back to a
32 0.8.x release you might get a blockchain validation error when starting the
33 old release (due to 'pruned outputs' being omitted from the index of
34 unspent transaction outputs).
36 Running the old release with the -reindex option will rebuild the chainstate
37 data structures and correct the problem.
39 Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan
40 the blockchain for missing spent coins, which will take a long time (tens
41 of minutes on a typical machine).
